Link of system

Link of system represent link media between one system with the other system, output of subsystem will become input for the subsystem of the other through link.

Input of System

Input is result of from process of energy to become output which good for and rest of dismissal, output can in the form of input for other subsystem,

Processing of system

An system can have a[n part of processor to change input become output, a[n production system will process input in the form of raw material and other materials become output in the form of finished goods

Target of System

system have target and target if a system don't have the target of hence operation of system of no use, and target told to succeed the goal or target of system come real

Elementary concept of information

less getting system of information will become cretin and finally end, source of from information is data, data represent plural form from is singular, data is fact depicting a[n occurrence and unity of reality, occurrence is something that happened at the time

Information is data which in processing to become more form good for and more meaning to accepting

Information cycle

Data represent form which still raw so that require to be processed by more processed data continued pass an model to be yielded information

Data processed to produce information use an certain model, for example data of temperature room they got is in set of Fahrenheit degree and this data enter in the form of less of berate to its ordinary receiver accept with set of Celsius degree, processed data become an receiver information model later; then accept the information, and make a n decision and conduct action , meaning to yield another action to make the amount of data return them. The data will

Catching as input and will be processed again pass a[n model and so on form a cycle,

Quality of from an information depended from three things that is information have to be accurate, punctual, and relevant

1. Accurate is information which must from mistake and cannot mislead, accurate also mean information be clear express its intention ;

2. On time is information which is data at receiver may not be tardy [of] information cause represent the basis for in decision making. When overdue decision making, hence can cause fatal for organization

3. Relevant [is] the information have benefit to wearing it. Information Relevance to everybody one with its different

Information System is an system in a organization bringing into contact requirement of processing of daily transaction, supporting operation, having the character of managerial and activity of strategy from an organization and provide certain outside party with needed report

Information value

Value Information determining from two matters, that is its opinion expense and benefit, Information will be valuable if big added significance of expense get it, however needing paying attention that information system is generally used for a few usefulness. To be more continue him most information cannot right across assessment assess its effectiveness
